acoustic absorption material in the boot (specification, page 9).
Representative independent claim 32 and dependent claim 19
are reproduced below:
32. A portable computer microphone for receiving
acoustic signals and generating a directional response
associated with a desired polar pattern, comprising:
a microphone element for receiving acoustic
signals; and
a boot for mounting and isolating said microphone
element, said boot configured to achieve a desired
microphone directional response associated with a
particular polar pattern to compensate for noise
sources internal to a portable computer.
19. The portable computer of claim 13, the position of
said microphone element defining a front distance and a rear
distance, the front distance being the distance between said
microphone element and said front shell surface, and the
rear distance being the distance between said microphone
element and said rear shell surface, wherein said front
distance and said rear distance are varied to achieve a
desired microphone directional response associated with a
particular polar pattern.
